Imagine someone trying to attack you by simply ordering many paid-on-delivery services to your house... man, wouldn't it be great that to order something like that you had to do a bit more validation or proving you say who you are? Oh wait, that's exactly what is happening. (as a side-effect)

I also don't understand the “Large Pizza for Pickup” bit, do you just get a random pizza? What size is 'large'? 25cm? 35cm? 40cm? more? What is on it? Cold fish and milk? Used car oil and yesterday's bread? This all seems to be hyper-personal and while that is fine, it doesn't really mean that everyone wants to order this way. Especially when you simply do not want to call or talk to someone.
